Sensing with Piezoelectric Ultrasonic Transducers | DigiKey
2023年6月15日 · Piezoelectric ultrasonic transducers provide a convenient and effective way to sense nearby objects and even measure their distance. They are reliable, easy to apply, and help designers avoid RF spectrum or EMI/RFI regulatory issues. They can also be used for non-contact measurement of fluid flow rates.
Ultrasonic transducer - Wikipedia
Ultrasonic transducers convert alternating current (AC) into ultrasound and vice versa. The transducers typically use piezoelectric transducers [3] or capacitive transducers to generate or receive ultrasound. [4] . Piezoelectric crystals are able to change their sizes and shapes in response to voltage being applied. [3] .
•A piezoelectric transducer (abbreviated XDCR): –uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge.
